You will now have the opportunity to enter filesystem information.
|
|
You will be prompted for device name and mount point (full path,
|
|
including the prepending '/' character).
|
|
|
|
Note that these do not have to be in any particular order. You will
|
|
be given the opportunity to edit the resulting 'fstab' file before
|
|
any of the filesystems are mounted. At that time you will be able
|
|
to resolve any filesystem order dependencies.
